GALFAD

• Separation
• Wet- waste to anaerobic digestion
• Dry-waste to pyrolysis
• Bio-solids to compost
• Biogas and syngas to electricity

ANAEROBIC DIGESTION

ANAEROBIC DIGESTION
Anaerobic digestion is a biological process for
converting organic materials into a combustible
gas It normally takes place in a wet environment
and in the absence of any air Organic materials
are broken down to produce methane and carbon
dioxide

ACCEPTABLE WASTE TYPES

Summary

• Every site is unique
• Of critical importance is the specific waste
  composition and in particular the moisture
  content
• 100 tonnes per day of feedstock (typically 175
  tonnes per day of waste) will generate 2.5 MW of
  power
